The Book of Prayer
And in a narration of Muslim:
"We used to offer the Friday prayers with him [Allah's Messenger (ﷺ)] when the sun passed the meridian. We would then return and try to find the afternoon shadow.
وَفِي لَفْظٍ لِمُسْلِمٍ: { كُنَّا نَجْمَعُ مَعَهُ إِذَا زَالَتِ اَلشَّمْسُ, ثُمَّ نَرْجِعُ, نَتَتَبَّعُ اَلْفَيْءَ } 1‏ .‏


‏1 ‏- صحيح.‏ رواه مسلم (860)‏ (31)‏.‏
